' tion.

My invention relates to improvements in explosive turbine engines, and consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure 1 represents an end View of my improved engine; Fig. 2 is a section on line w% of Fig. 1; and Fig. 3 is a side elevation.

Referring to the drawings, A represents the casing of the engine, in one end of which is positioned a turbine wheel 2 mounted upon a shaft 3 extending through an adjacent end Wall, the opposite end of the casing including a chamber 4 separated from the turbine by a valve 5 mounted upon a valve stem 6 extending through the adjacent end wall. The outer end of the stem 6 carries a piston 7 slidable in the pocket 8, the stem 6 being normally pressed outward to hold the valve 5 closed by the spring 9 interposed between the end Wall of the casing and the nut 40. Air openings 10 for the pocket are provided in connection with which works a spring pressed rvalve 11 normally adapted to be pressed outward by the spring 12 to control the passage of air through said openings.

Actuated from the shaft 3 by an eccentric 13 is a piston 14 slidable in the piston chamber 15. The piston chamber 15 communicates through a port 16 and conduits 17 with a reservoir 18. The port 16 is normally closed by a spring pressed valve 19. The chamber 15 further communicates by ports 20 and 21 with conduit 22 leading into a carbureter 23 of usual construction. The port 20 is normally closed by a spring pressed valve 24. The port 21 is held normally open by a spring pressed valve 25 which connects with a piston 26 slidable in the piston chamber 27. The piston chamber 27 is connected by a conduit 28 With the reservoir 18. An outlet conduit 29 leads from the reservoir 18 to the port 30, opening into the bottom of the chamber 4, the port 30 beingrnormally closed by a spring pressed valve 31. Positioned in the top of the chamber 4 is a spark point 32. Electrically connected with the spark point 32 is a pole 33 supported above the engine and a slidable pole 34 supported in the top of the engine, the slidable pole being normally held pressed down by a spring 35. When pressure Within the chamber 4- acting upon the piston 36 supporting the slidable pole raises the same to make contact with the pole 33 a spark is formed at the point 32.

In operation, with the storage chamber full of carbonated air at certain pressure, said carbonated air will be forced by its pressure past the valve 31 to fill the chamber 4. -As soon as it reaches the proper pressure in the chamber it will force up the piston 32, closing the contacts and causing an explosion, which explosion will open the valve 5 and operate the turbine, exhausting through the exhaust port 37. This rotates the shaft 3 and causes the pumping of the carbonated air through the carbureter and port 17 to the chamber to keep up the pressure. The pressure in the chamber is kept from going beyond a certain point by the shut off valve 25. Gasolene may be fed to the carbureter in the ordinary manner. As soon as the explosion chamber has been freed of its charge a new charge will pass through into the chamber past the valve 31 for a second explosion. The ports 10 allow the air to pass slowly from the pocket 8 to allow slow clos ing of the valve 5 to permit the gases to throughly pass out of the chamber to the turbine. In the opening of the valve 5 the suction action of the plunger 7 will open the valve 11 to draw air in through the openings 10. I provide the casing above the turbine with a spring pressed valve 38 closing the ports 39 which allows the sucking action of the turbine to draw in air to cool the blades.

I claim as my invention: An explosive turbine of the class described supported upon the outerend of said stem,

a pocket receiving said piston, said pocket being formed with an outer valve opening,

and a spring pressed valve normally closing 10 said opening.

In testimony whereof I aflix my signature in presence of two Witnesses.
